I have no idea what "their manner of using the toilet" even means.  I know that some British folks wonder why Americans call it the "restroom" or "bathroom" instead of toilet though.  I have a feeling that might have been misconstrued into what you heard.  It's all just so silly.

I have several friends across the pond. While one of them is still rather annoyed about that little colony thing, none of them seem particularly concerned about  the "Lou" practices of Americans. 

Put chalkboard tiles.  Then you can draw while in the drawing room.
